Answer:

It tell us that it's necessary 2 moles of Ag in the stoichiometric proportion of the reaction.

Explanation:

The equation of a chemical reaction is a representation of the ideal reaction: 100% yield of the products and without parallel reactions. So, the equation presents the stoichiometric quantities of the substance. For example, for a generic reaction:

A + 2B → 3C

It says that it's necessary 1 mol of A and 2 moles o B to form 3 moles of C. Thus, the numbers before the substances represents the stoichiometric number of moles of that substance.

Relation between glancing and angle of deviation

shtirl [24]

Answer:

the Glancing angle is the angle between the incident ray and plane mirror which is 90o in the given case. The angle between the direction of the incident ray and the reflected ray is the angle of deviation. Since the angle of deviation for a plane mirror is twice the glancing angle, the angle of deviation is 1800.

Answer: (a) The reaction mixture will proceed toward products.

Explanation:

Equilibrium constant is defined as the ratio of pressure of products to the pressure of reactants each raised to the power their stoichiometric ratios. It is expressed as $K_p$

K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

For the given chemical reaction:

$2A(g)\rightleftharpoons B(g)$
